Email open rates by day of the week

I'd like to be able to see the percentage of opens and/or click-throughs by day of the week. We have several campaigns that are trigger-based with emails being sent after an activity is performed. Currently I know I can select a specific day, but if we could see overall the rates based on the specific day it was sent, I think it could be helpful. 

I know that Google Analytics has this feature to some extent, and I could build it out by exporting to Excel, but a straightforward visual representation would be immensely helpful.
